A stopper 225 is formed between the guide groove 222 and the retaining groove 224 to prevent the retaining member 141 from moving towards the guide groove 222.

One end of the atomizer 1 is provided with a first outer electrode 11, a first inner electrode 12, and a first insulating sleeve 13 located between the first outer electrode 11 and the first inner electrode 12, and the first outer electrode 11 is arranged outside the first inner electrode 12. The first outer electrode 11 and the first inner electrode 12 are both electrically connected to an electric heating wire 14 in the atomizer 1. The retaining member 141 is provided on an outer peripheral surface of the first outer electrode 11. Preferably, there are at least two retaining members 141, which are located symmetrically at two sides of the first outer electrode 11, thus the connection is more reliable. An atomizing seat 15, an air pipe 16 sleeved on one end of the atomizing seat 15, a liquid storage cotton 17 arranged outside the air tube 16, and a liquid guide cord 18, configured to convey liquid in the liquid storage cotton 17 to the electric heating wire 14 to be atomized, are provided inside the atomizer 1.

The electronic cigarette device further includes a force applying mechanism for applying a force on the atomizer 1 in a direction away from the battery rod 2. Due to the force applying mechanism, the connection between the atomizer 1 and the battery rod 2 is more stable, which may prevent the connection being loosen and prevent the atomizer 1 from being disengaged from the battery rod 2.

The force applying mechanism is an elastic second inner electrode 21 configured to be electrically connected to the atomizer 1 and a battery 24 in the battery rod 2. The second inner electrode 21 is provided on a groove wall of the engaging groove 221 and is configured to elastically abutting against an end surface of the atomizer 1.

The second inner electrode 21 includes an abutting member 211 configured to abut against the end surface of the atomizer 1, a fastener 212 movably connected to the abutting member 211, and a spring 213 arranged inside the fastener 212 and abutting against both the abutting member 211 and the fastener 212. The fastener 212 is electrically connected to the abutting member 211 and the battery 24. The abutting member 211 is configured to abut against an end surface of the first inner electrode 12, thus the electrical connection between the atomizer 1 and the battery rod 2 is more stable and reliable.

A second outer electrode 22 made of metal material is arranged outside the second inner electrode 21, and a second insulating sleeve 23 is provided between the second outer electrode 22 and the second inner electrode 21. The engaging groove 221 is provided at one end of the second outer electrode 22. The second outer electrode 22 is configured to be electrically connected to the atomizer 1 and another electrode of the battery 24. The second outer electrode 22 is configured to abut against the first outer electrode 11 of the atomizer 1 to realize the electrical connection therebetween.

The guide groove 222 and the stopper 225 are provided on an inner wall of the second outer electrode 22. An end surface of the second insulating sleeve 23 is provided with a gap 231 at a position corresponding to the guide groove 222 and the stopper 225, and a space enclosed by the gap 231 and the stopper 225 forms the directing groove 223 and the retaining groove 224. Preferably, the battery rod is provided with at least two guide grooves 222, two directing grooves 223, two retaining grooves 224 and two stoppers 225 corresponding to the retaining members 141. The second outer electrode 22 may be made of a conductive metal material such as copper, the second insulating sleeve 23 may be made of a non-metallic material such as silica gel or rubber, and the directing groove 223 and the retaining groove 224 are formed by the cooperation between the second outer electrode 22 and the second insulating sleeve 23, thereby reducing the material of the second outer electrode 22, reducing the cost and facilitating manufacture.

Reference is made to FIGS. 5 to 7, wherein FIG. 5 is a schematic view showing the structure of the battery rod 2 of the electronic cigarette device according to a second embodiment of the present application; FIG. 6 is a schematic view showing the structure of a second outer electrode 22 of the battery rod 2 in FIG. 5; and FIG. 7 is a schematic view showing the structure of the second outer electrode 22 in FIG. 6 viewed from another angle. Unlike the first embodiment, in the second embodiment, the retaining groove 224 is provided on the inner wall of the second outer electrode 22, a stopping step 226 is formed on the inner wall of the second outer electrode 22, the end surface of the second insulating sleeve 23 abuts against the stopping step 226, and a space enclosed by a portion, corresponding to the stopper 225, of the end surface of the second insulating sleeve 23 and the stopper 225 forms the directing groove 223. Since the stopping step 226 is formed on the inner wall of the second outer electrode 22, there is no need to adjust the position when assembling, that is, it is only required to insert the second insulating sleeve 23 into the second outer electrode 22 until abutting against the stopping step 226, thus it is easy to assemble.

Reference is made to FIG. 8, which is an exploded schematic view showing the structure of the electronic cigarette device according to a third embodiment of the present application. Unlike the first embodiment, in the third embodiment, the force applying mechanism includes a first magnet 19 arranged at one end of the atomizer 1, and a second magnet 25 arranged at one end of the battery rod 2. The spring 213 in the first embodiment is replaced by a silica gel member. The first magnet 19 and the second magnet 25 repel each other when the atomizer 1 and the battery rod 2 are connected, thus the retaining member 141 may be reliably clamped in the retaining groove 224. It is understood that, on basis of the first embodiment, the first magnet 19 and the second magnet 25 are respectively arranged on the atomizer 1 and the battery rod 2, thereby solving the defect that the spring 213 is prone to fatigue failure.

In summary, in the electronic cigarette device according to the present application, the side wall of the engaging groove 221 is provided with the guide groove 222 extending in the radial direction of the battery rod 2, the directing groove 223 extending in the circumferential direction of the battery rod 2 and in communication with the guide groove 222, and the retaining groove 224 for accommodating the retaining member 141 and extending from one end, away from the guide groove 222, of the directing groove 223 towards the end surface of the battery rod 2; and the stopper 225 is formed between the guide groove 222 and the retaining groove 224 to prevent the retaining member 141 from moving towards the guide groove 222. When assembling the electronic cigarette, the retaining member 141 of the atomizer 1 may be inserted into the battery rod 2 via the guide groove 222, then the atomizer 1 is rotated to move the retaining member 141 into the retaining groove 224 along the directing groove 223, thus one end of the atomizer 1 may be inserted into the engaging groove 221, in this way, a reliable connection between the atomizer 1 and the battery rod 2 is ensured, and the whole assembly structure of the electronic cigarette device is more stable and reliable. Furthermore, such structure is simple, easy to manufacture and facilitates connection.
